above described, as illustrated, correspond with those used at present in the tape of ins chine known as the Oliver.

Referring now more particularly to the form of the device illustrated in Figs. 3 to hoth inclusive, 0 indicates an annular meniher or disk carrying an index linger or pointer D and whichv is nrountedon the frame of the machine or carriage concentrieally with the platen shaft and is adapted to he turned or rotated by hand. Said disk C is shown in the drawing as mounted on the end of the hearing sleeve 1% which is extended outwardly from the frame plate ll to receive it. Said disk C is, for convenience, provided with circumferentially spaced graduations or scale marks spaced at uniform angular distances apart to correspond with the line space movements of the platen. The index finger or pointer D is secured to the disk at the zero n'iark of the Said disk C is, moreover, en god with the part of the frame on which it is mounted by means adapted to hold the disk from freely turning relatively to the frame, but permitting rotative adjustment of said disk on the said frame. E indicates an index finger or pointer mounted to more concentrically with thedisk C which is adjustable circuinferentially on or relatively to said disk and is adapted to turn with the disk; said finger or pointer E that it 111% he placed in Varying angula positions with respect to the pointer D or zero point of the disk and heing connected with the disk so that it will remain at any point to which it may he moved or adjusted and will then turn with the disk when-the latter is retated. by the hand of the operator. F indicates an index finger or pointer which is at tached to and turns'with the platen shaft or platen and is adapted to ce.-a ct with, the pointer l) or zero mark of the disk andthe adjustable pointer E of said disk.

So far'as the general ends to be attained are concerned the disk C may hc engaged with its hearing on'thc fraine,"in theinstance illustrated, the stationaryslee i 'B, by any device adapted to hold the disk froni ireely turning while permitting its retative adjustment, and the index finger or oointer E may be connected with the disk C )3; any means adapted to retain the same in any position in which it may he placed with respect to the pointer l) or zero mark of the dis Z, while on ahiing pointer E to be readily shifted or sing adjustable so g i D 7 929,242

adjusted, relatively to said pointer D or zero mark, circumferentially of the disk. In the preferred embodiment of my invention illustrated in the drawing, the disk C is frictionally engaged with the sleeve 13 while the pointer E is mounted on an arm which turns on the sleeve 13 and is held'in adjusted position on the disk by an interlocking connec tion with the disk or by a locking device adapted to hold said pointer to the disk so that it will turn with the latter.

Now referring to the details of construction in the features above referred to illustrated in Figs. 1 to 5 of the drawings: G indicates a collar which surrounds the outer part of the sleeve 13 and is rigidly secured thereto by screws as shown or otherwise. At its inner end said collar G is provided with an an nular flange g. The disk 0 fits upon or around the collar G and in its inner face is formed an annular recess adapted to receive the flange g on the collar G. Between the bottom of said annular recess and said flange is located a concave, elastic ring or springwasher H. Attached to the inner face of the disk by screws or otherwise is a ring I which overlaps the flange g and serves to prevent. outward movement of the disk relatively to the frame and to thereby maintain the springwasher H in compression between the disk and flange. The said concave washer H thus confined between the disk and the said flange g ex'ert's constant pressure on both of said parts by which is afforded frictional resistance to the turning of the disk so that the disk may be readily turned by hand but will remain in any position to which it may be turned. The pointer E is attached to an elastic or spring-arm e formed on or secured to a flat ring e which fits or is held within. a groove formed between the inner end of the stationary collar G and a ring G which is applied around the sleeve B and is held in place thereon by the stationary collar G. The pointer E is adapted to be turned or rotated on the sleeve B by the turning of the ring in said groove.

For locking the pointer Eto the disk 0 the latter is provided around the margin of its inner face with a flange c which is provided with radial notches c, spaced to correspond with the scale-marks on the face of the disk, and the arm (2 is provided near its outer end with a holding tooth 0 adapted to engage either one of said notches c and which ressed toward the disk and held inv interocking relation with one of said notches c by the resiliency of the spring-arm c. The pointer E has the form of a horizontally-and outwardly bent extension of the arm 0 which projects over the marginal surface of the disk C with its outer end adjacent to the scale marks (on the outerface of the disk. To

permit the pointer E tohe easily moved or shifted and the arm 6 m be read ly pressed rearward for the disengaging of its tooth e from the notches 0 said pointer is provided with an outwardly extending arm or fin piece a located at one side of the pointer and projecting forward or outside of the outer face of the disk C. By applying the linger to the finger-piece e" and pressing backwardly thereon the arm 6 is released from its lo cl iing engagement with the disk and the pointer may then be moved or shifted by the action of the finger on the linger-piece in a inanncl to turn the pointer around, or move it along:

the periphery, ol the disk. i.

The pointer F is shown as having the form of a small metal arm secured to the hub or sleeve a by which the turning knob A is securedto the shaft a. i

The disk C is preierabl roughened or knurled on its peripheral surface so that it may be readily turned by hand.

The operation. of the indicating device described will be understood. from the following: The general purpose of the line space ind icating device is to indicate to the operator the extent to which the platen must be turned backward when inserting a sheet oi paper into the machine, in order to bring the first line of printing the desired distance from the top margin of the paper, according to the space occupied by-the heading on the sheet. More particularly, .the indicating device is designed for use in cases where it is desired to make out a number of" bills or invoices and to make carbon copies ol the same on a single strip or long sheet of paper. In a case of this kind, it is desirable that the copies should be spaced as closely as possible on the record strip but at uniform distances apart,. or with equal spaces between several records or copies, and the indicatingdevice is employed to enable the operator to readily insert a new sheet for each separate original bill or invoice in such manner that the first printed line of the carbon copy on the record 'sheet shall be located at a desired distance from the last printedline of' the preceding carbon copy thereon. As, l'or instance, supposing the record strip' and a sheet of paper for the original bill or invoice has been togcthcr inserted into the inaciiine with carbon paper between them, the first bill. or invoice may be printed and the carbon co )y will be made in the usual manner on the record strip. The printing of the bill or invoice having been completed, the platcn will then be turned to carry the original shcct out ol" theinachinc, and thc p .ttcn then turned backwardly to i JOVQ or shift the record strip backwardly to such a point which, when a new sheet is inscrtcd, the part of the new sheet on which the lirst line is to beprintcd, will be located at such distance from the last line ol the carbon copy as to lcavc a desired space on therecord strip between the copies.

In using the indicating devise described represented by the op erator setsthe pointer E at a distance from the pointer Dor zero mark on the disk C, equal to the distance which itis-necessary to turn the platen backward after printing theflast line of one bill or invoice in order to start a new original sheet into the machine in .such manner that'the first line of the next bill or invoice when started at its proper placeon' the sheet will, on the carbon copy sheets-come at a distance desired as 2 3, or 4 line spaces from the last line of the preceding carbon co y. lhe setting of the pointers may be e .ected as follows: In the case of an Sliver typewriter, one of the original sheets or-blanks for a bill or invoice, which usually has a printed heading, is inserted in the machine with its advance margin against the lower guide roller or gripping roller by which the sheet is fed forward, and in position to be gripped and fed forward when the platen is turned in its usual feeding direction. The pointer F will, at this time, extend in anydirection from the platen shaft that itmay-happen to stand, aud'the disk is then P turned to bring; its zero mark op posite the said pointer F and there allowed to remain. The

platen is then turned the first line, which is usually the date line The platen is then turned forward a space of two or three additional lines according to the distance desired between the carbon copies on the record sheet. The operator, leaving the disk 6) in the same position at which it was first set, releases the pointer E from the diskand turns said pointer until it is oppo-' site or coincides with the pointer F in the new osition of the latter. The angular distance lietween the zero mark or pointer D and the pointer E will then be equal to the distance which it is necessary to turn back the platen for inserting a new sheet, this distance bein the length of the heading on the blank bil or inyoice plus the distance around the platen 3. an the grip ing roller to the striking point of the type, pliis the sp'iicc to;l y left between thecarhon copies on the record sheet. The parts will now be adjusted for use in connection with the same bill .orinvoice heads or sheets, so long as it may be desired to use the same.

in: the use of the device in printing, the

billiniinyoice sheet, and the record sheet are inscrtcdirrto the machine, with the carbon paper between them, in the-usual manner. Afte'rthe printing of the first invoice is finis'li n', on com tion. The platen will then beturned forward far enough to remove the original sheet and then turned backward until the pointer ll is carried past the pointer E and around it heklisk until it reaches the zero mark or to feed the paper forward until brought into position for printing next original sheet which will be inserted by thrusting it into the machine until its top edge comes inv contact with the first guide roller by which the sheet is gripped to the platen, and the platen will then be turned forwardlv to carry the record sheet and the new original sheet into position for printing the first line on said new original sheet.

'It follows that, by ti o use of the device described, the operator having once deter-- mined the angular distance or umber of line spaces through which the platen must be turned baekwardly before starting a new sheet into the machine, in every instance, or when inserting'cach new original sheet for an original bill or invoice, is enabled to invariably turn the platen backward the same distance, according to'the angular distance between the zero-mark or pointer I) and the pointer E on the disk. The operator will thus be able to invariably the first printed line of each carbon copy on the record sheet at the same distance from the last printed line of the previously made copy on said record sheet, thereby leaving uniform spaces between the several carbon copies on the record sheet.

The graaluations or scale-marks on the disk C are not essential or necessary but are useful on'ly'to enable the pointer E to be set by the operator in desied positions fororiginal sheets having headings of different widths, when the operator knows from recollection places. on the scale at which the. pointer must be located for the different original sheets. Moreover, as the graduations correspond'with the line spaces, if the operatordesires to make the spaces between carbon copies greater or less thiscan be done by merely shifting the pointer E backward or forward one or more spaces as dtsired.

Inasmuch as the angular distance between the pointers D and E will, in any'case, correspond with. the extent of backward turning movement of the platen requircdsit is immaterial whether the pointer D or zero mark, or the adjustable pointer E be used to mark the startin noint of the backward :n l turning movement. It is somewhat morpconvenient, however, in first effecting ail justinent ofthc pointer E that the scale be numbered from the zero mark in the manner indicated or like the numbering on a clock dial so that the numbers shall indicate the extent of lorward mcvcment'ol the platen and in that case in turning the platen back ward, in inserting a new original sheet, the" operator w1ll start lrom the pointer E and turn back to the Zero-mark or pointer D.

The graduations or scale marks on the disk being used merely for convenience in setting the pointer E from memory and not being necessary for use in setting the adjustablc pointer, the disk C and its graduations may be omitted and, in that case the pointer l or the zero ma1 k on the disk may be nat'laced by an indicating: arm or pointer 5 fl.;l:tfl=i-'.-Il to (o-act with a like pointer having angular adjustment with respect to the tirst pointer, both of said pointers being adapted to be turned, orio have rotative adjustment tegerlu-r, on the machine frame.

A constructirm of this latter kind is shown in digs. 6 and 7. In this instance, a rotative collar surroi. ids the sleeve 13 and has attached to its inner end a flange to which is attached pointer ii. (in the collar J is 5 mounted a ring-ll to which is attached. a pointer M. On the outer end of the collar J is secured a ring; 5 knurled at its edge to enable said collar and the pointer K to be readily turned on the sleeve B Frictioi'ial 0 connection between the collar J and the sleeve 3 is afforded by means of a concave spring: metal ring or washer il inserted between the flange on the inner end of said colla r and a fixed ring 0 on the said sleeve 5 B The collar J is held from endwiso movemcnt on the hub B by means of a ring b socured to the outer end of the hub within the outer end of the ring J. Frictional connection between the ring L and the collar J will 0 be afforded by means of a like spring-washer P interposed between the flange and the said ring L. The platen shaft will, in this instance, have a ppinter l affixed thereto in the same manner before described. The

5 operation of the form of the device shown in said Figs. 6 and '7 \ill be the same as that 'of the form first described; the distance through which the platen must be turned backward to givc uniform spaces between 0 the carbon copies on the record sheet being determined by the angular distance apart of the relatively adjustable pointers K and M which-are adapted to. be turned together by the fingers of the operator applied 'to the 5 knurled ring 5 The original setting of the pointers K and M in this form of construction may be conveniently effected as follows: One of the sheets, with a printed heading, on which the bill or invoice is to be printcd, is placed in the machine with its upper edge in position-to be gripped by the first guide roller. The collar d and pointer K will then be turned to bring said pointer K opposite the revolving pointer F. The

a platen will then be turned forward to carry the sheet into position for printing the first line thereon and two, three or four additional linespaccs as required for the distance between the carbon copies on the record sheet. The pointer M will then be turned on tfie sleeve J until it reaches a position cnm'tliriing with the new position of the pointer F, and the distance between the two pointers Mand K will then indicate the an gular distance that the platen must be 'turned backward in inserting each new or additional sheet, as before described.
